Our top 8 electrical companies in Houston

Each entry explains why the company was selected, what it does well and what to weigh before hiring.

  1. West Houston Electric

    panel, generator and EV charger work for Katy-area homeowners4.9(2544 Google reviews)21732 Provincial Blvd Ste 150, Katy, TX 77450Best for panel, generator and EV charger work for Katy-area homeowners    Rank01

    Why we picked them

    The review count is the standout here, and 4.9 across more than 2,500 reviews is hard to fake at that scale. What we would press on is the membership and financing side, which is heavily promoted and worth costing out honestly against a one-off repair. For panel, generator and EV charger work in the Katy corridor, this is a sensible company to have on a shortlist of three.

    What we like

    • 4.9 from 2,544 reviews on its Google Business Profile, read 28 September 2026
    • Broad residential range including panels, generators, EV chargers and pool wiring
    • Published hours are 24/7, useful for outages and dead circuits after hours
    • Family owned and trading since 1991 per its own website
    • Wide service area from Fulshear and Katy out to Sugar Land, Spring and The Woodlands

    Things to consider

    • Commercial and new-construction work is not emphasised, so confirm scope before booking
    • The $34 a month VIP membership and 0% financing are pushed prominently and need costing against the actual job
    • No published pricing, so get a written flat-rate or hourly quote and ask about after-hours charges

  2. Electrical Works of Houston

    permitted residential electrical projects like panel upgrades, rewires and generator installs in Houston5.0(80 Google reviews)409 Oriole St, Houston, TX 77018Best for permitted residential electrical projects like panel upgrades, rewires and generator installs in Houston    Rank02

    Why we picked them

    The builder-first history is the most useful thing on this profile. Nine years of new residential construction before opening a homeowner service arm in 2023 tends to produce electricians who plan work properly and expect an inspector to look at it, and the flawless 5 star record across 80 Google reviews suggests the transition has gone well. The limitation is plain enough: weekday hours only, so book ahead and call someone else at midnight.

    What we like

    • Nine years of residential new-construction and builder work before launching the homeowner service arm
    • 5 out of 5 from 80 reviews on its Google Business Profile, read September 28, 2026
    • Texas licence numbers published openly, TECL #29993 and TMEL #305440, verifiable through TDLR
    • Covers both planned projects and diagnostic repair calls, including generators and panel upgrades
    • Affiliated HVAC company means heating and air can be handled through the same contact

    Things to consider

    • Published hours are 8 AM to 5 PM weekdays with Saturday and Sunday closed, and no emergency call-out is advertised
    • Presents itself as residential only, so commercial and industrial work is likely out of scope
    • No pricing, flat rates or warranty terms are published, so get figures in writing before booking

    • Panel upgrades

  3. A1 Plus Electrical, Plumbing and Air Conditioning Repair

    Houston homeowners needing 24-hour electrical, AC or plumbing help from one contractor4.8(5443 Google reviews)15110 Northwest Fwy #190, Houston, TX 77040Best for Houston homeowners needing 24-hour electrical, AC or plumbing help from one contractor    Rank03

    Why we picked them

    A 4.8 average across more than five thousand Google reviews is unusual, and it points to a high-volume operation with the dispatch discipline to keep most jobs on track. The three-trade model is genuinely useful in a city where heat, humidity and shifting clay tend to break several systems in the same house. Just pin down the flat-rate number and the permit responsibility before anyone starts work.

    What we like

    • 4.8 stars from 5,443 Google reviews as of September 28, 2026, an unusually large sample
    • Electrical, HVAC and plumbing handled by one dispatch desk
    • Published hours of 24 hours a day, every day, including emergency call-outs
    • Generac and Kohler dealer with generator installation, repair and financing
    • Master electrician licence number TEML248472 published on its own website
    • Flat-rate quoting and same-day service advertised, with financing options

    Things to consider

    • The website advertises a 4.9 rating while the Google profile shows 4.8; use the Google figure
    • Flat-rate pricing can exceed an independent's hourly charge on very small jobs
    • Plumbing scope reads narrower than the electrical and HVAC lists on the published site
    • At this volume you may not get the same technician on repeat visits

    • Lighting installation

  4. Mister Sparky Electrician Houston

    homeowners needing 24/7 emergency electrical repair or a panel upgrade in Greater Houston4.7(1257 Google reviews)600 Century Plaza Dr # C110, Houston, TX 77073Best for homeowners needing 24/7 emergency electrical repair or a panel upgrade in Greater Houston    Rank04

    Why we picked them

    The combination of genuinely round-the-clock hours and a 4.7 rating across more than 1,200 Google reviews is a solid signal, particularly for a franchise operation where quality can vary by territory. The guarantees are attractive but they are the company's own terms, so read them on the work order rather than the website. Best value here is the emergency and panel work, less so the small one-hour jobs an independent would quote cheaper.

    What we like

    • Published hours show 24 hours a day, seven days a week, with emergency response treated as a core service
    • 4.7 rating from 1,257 reviews on its Google Business Profile, read September 28, 2026
    • Says it has served Greater Houston since 2003, so a long local track record
    • Range covers both older-home problems like aluminium wiring and newer needs like EV chargers and generators
    • Offers standalone safety inspections and home electrical surveys, handy after a property purchase
    • Advertises upfront estimates, an on-time guarantee and a 100 percent satisfaction policy

    Things to consider

    • The on-time, pricing and satisfaction guarantees are the company's own published claims and are not independently verified here
    • Franchise pricing on small jobs is often higher than an independent local electrician's hourly rate
    • Published material reads as residential throughout, with no clear commercial or industrial offer
    • Website phone numbers differ from the listed profile number, and one page references the Katy location, so confirm coverage for your address

  5. Lumens Electric LLC

    aluminum wiring and panel upgrade work in older Houston homes4.8(162 Google reviews)Best for aluminum wiring and panel upgrade work in older Houston homes    Rank05

    Why we picked them

    The service list points at real Houston problems rather than generic filler, and leading with aluminum wiring replacement suggests the firm knows which houses keep calling. A 4.8 average from 162 reviews, read in late September 2026, is a solid body of evidence. We would ask about the 2006 start date versus the 34 years of experience claim, and get the TECL number confirmed before work starts.

    What we like

    • 4.8 rating from 162 Google reviews as of September 28, 2026
    • Aluminum wiring replacement and panel upgrades listed as core services, not sidelines
    • Covers repairs, remodels and new construction, so one contractor can handle a long list
    • Generator and EV charger installation offered alongside everyday electrical repairs
    • Trading since 2006 per its own website, with BBB, Yelp and Facebook profiles to cross-check

    Things to consider

    • Website cites both a 2006 start and over 34 years of experience, worth clarifying on the call
    • Licence status and award claims come from the company's own site, so verify the TECL number
    • No pricing published, and 24/7 emergency response usually carries an after-hours premium
    • Likely a better fit for residential and light commercial work than heavy industrial projects

  6. Zuniga West Electric LLC

    high-ceiling fixture and fan installation in Houston-area homes4.9(150 Google reviews)Best for high-ceiling fixture and fan installation in Houston-area homes    Rank06

    Why we picked them

    The review record here is unusually consistent for an owner-led shop, and it points in a specific direction: fixture and fan work in homes with awkward ceiling heights, done in one visit and priced competitively. That is a narrower recommendation than the full service list implies, and we think it is the more useful one. Confirm licence details and permit responsibility in writing, as you would with any contractor, and ask how the HVAC side is actually staffed.

    What we like

    • 4.9 rating from 150 Google reviews, read on September 28, 2026
    • Reviews repeatedly cite high-ceiling fan and chandelier installs done safely in one visit
    • Owner-led, so the person quoting the job is often the person doing it
    • Free, no-obligation quotes advertised
    • Broad service footprint covering Houston plus suburbs within roughly 45 miles
    • Covers both one-off residential jobs and ongoing commercial building maintenance

    Things to consider

    • No 24-hour emergency service advertised, so after-hours availability is unclear
    • HVAC is listed alongside electrical work; worth asking whether that is in-house
    • Licence and insurance details are not published in the material reviewed, so request them directly
    • A small operation, which can mean less same-day availability than large multi-crew firms

    Services

    • Rewiring
    • EV charger installation

  7. Trizone Electric LLC

    EV charger and standby generator installations in Houston homes and commercial sites4.9(76 Google reviews)10400 Westoffice Dr #114, Houston, TX 77042Best for EV charger and standby generator installations in Houston homes and commercial sites    Rank07

    Why we picked them

    The review pattern here is unusually clear. This is a contractor that has built a genuine EV charger practice in Houston and is trusted for generators, while also chasing larger commercial and industrial contracts, and the Google feedback at 4.9 from 76 reviews is recent and consistent rather than historic. Clarify whether the 24-hour listing means true after-hours dispatch or just an answering line, and ask about the panel before you commit to a charger price.

    What we like

    • 4.9 rating from 76 Google reviews, read on September 28, 2026
    • Strong, repeated review feedback on EV charger installs, including named technicians
    • Covers residential, commercial and industrial work under one contractor
    • Generator installation plus ongoing maintenance and repair, useful after Houston storm season
    • Advertises 24-hour emergency electrical response
    • Specialist claims in data centre, medical and nursing facility electrical work

    Things to consider

    • Google lists open 24 hours daily while the website lists office hours of Monday to Friday 8am to 5pm, so confirm after-hours availability
    • No pricing, licence number or warranty terms are published in the material reviewed
    • A firm geared to larger contracts may not be the cheapest option for a single small repair

  8. JN'L Electric - Houston Electricians 24/7 | Electrical Contractor

    commercial generator service and after-hours electrical repair in northwest Houston4.8(80 Google reviews)13502 E Cypress Forest Dr, Houston, TX 77070Best for commercial generator service and after-hours electrical repair in northwest Houston    Rank08

    Why we picked them

    A mid-sized, family-run outfit with genuine breadth, and the commercial generator and facility maintenance work is the part that sets it apart from the many Houston shops that stick to residential service calls. The 4.8 rating from 80 reviews reads as steady rather than spectacular, which is usually a good sign at that volume. Confirm the state licence number and the after-hours rate structure on the first call and you will know quickly whether the fit is right.

    What we like

    • Published hours list phone coverage around the clock, seven days
    • 4.8 rating from 80 reviews on its Google Business Profile, read September 30, 2026
    • Covers both residential service work and commercial buildouts, lighting and facility maintenance
    • Generator installation and repair handled in-house for commercial, residential and portable units
    • Describes itself as a second generation, woman-owned business with around ten technicians

    Things to consider

    • Licence, insurance and bonding are the company's own claims, so verify the TDLR number directly
    • After-hours callout pricing is not published, worth confirming before a night or weekend visit
    • Based in northwest Houston, so travel time may count against jobs on the far south or east side
    • Review volume is modest next to the heavily advertised regional franchises

    Services

    • EV charger installation
    • Generator installation

How to choose a electrician in Houston

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope
